[0016] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model; obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0017] Please refer to Figures 1 to 3 , a small motor test tooling, including a housing 1. A plurality of grooves 11 for placing small motors are sequentially and stepwise opened from top to bottom at the top of the housing 1. The width of the grooves 11 gradually decreases from top to bottom. Two first long through holes 12 for the electrodes of the small motor to pass through are oppositely opened in the grooves 11. A test probe 2 capable of being connected to the electrodes of the small motor is arranged in the housing 1. A driving device capable of driving the test probe 2 to move so as to be adapted to the positions of the electrodes of the small motor is arranged in the housing 1. The utility model adopts the stepped grooves 11, which can be adapted to small motors of different sizes. At the same time, the driving device is used to move the position of the test probe 2, so that the test tooling can be adapted to the electrodes of the small motor, improving the versatility of the test tooling.

[0018] Preferably, the test probe 2 can adopt a commercially available retractable test probe 2.

[0019] Specifically, the driving device includes a connecting strip 31 and a gear 32. One side of the connecting strip 31 is connected to the test probe 2, and a rack 33 is provided on the other side and meshed with the gear 32. An internal gear ring 34 that can be meshed with the gear 32 is provided on the inner side wall of the housing 1. The test probe 2 is located in a second long through hole 35 inside the housing 1. Therefore, by rotating the internal gear ring 34, the gear 32 and the rack 33 can be driven to rotate, so that the test probe 2 can move in the second long through hole 35, so that the positive and negative probes of the test probe 2 are adapted to the positive and negative terminals of the motor.

[0020] Further, a stud 21 is provided at the bottom of the test probe 2. The stud 21 is threadedly connected to a wire harness fixing nut 4. A connecting through hole 41 penetrates through the bottom side wall of the wire harness fixing nut 4. A wire harness 5 is arranged inside the connection. The wire harness 5 is bent downward in an "L" shape. The cooperation between the wire harness 5 fixing nut 4 and the test probe 2 facilitates the fixing of the wire harness 5 and at the same time limits the upward movement of the test probe 2.

[0021] Specifically, the wire harness 5 is divided into a positive wire harness and a negative wire harness.

[0022] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
